Thermal cutoffs, commonly known as thermal fuses, are a type of circuit protection component designed to prevent electrical devices from overheating and causing fires. These components are essentially a safety mechanism that interrupts the electrical circuit by breaking the connection when the temperature exceeds a predetermined limit. Their main function is to provide reliable and swift protection by cutting off the power, ensuring the safety of both the electrical device and its surroundings.
Thermal cutoffs are primarily used in various household appliances such as coffee makers, hair dryers, and microwaves, as well as in office equipment and industrial machinery. The key characteristics of thermal fuses include their compact size, precise temperature control, and the ability to function effectively under high voltage and current. Prominent manufacturers of thermal cutoffs include companies like Schott, Bel Fuse, and Cantherm.
